Tech Five: This morning's tech stocks to watch

Jeff Bezos, CEO and founder of Amazon, at the introduction of the new Amazon Kindle Fire HD and Kindle Paperwhite personal devices, in Santa Monica, Calif., in 2012.

Welcome to Tech Five, our morning roundup of technology stocks that are either surging or slumping.

Here’s what to keep an eye on Monday:

Amazon. Keep this one on your radar all week. On Wednesday, the company is hosting an event to provide an update on their “video business.” Translation: this could be the day Amazon unveils the rumored set-top box for television. The move makes sense for Amazon, since it already hosts its own Instant Video streaming service.

King. Safe to say investors aren’t sweet on the creator of Candy Crush Saga. Since launching its IPO with a share price of $22.50, it’s been a steady slide for King stock. In pre-market trading, it’s on the rise (0.72%). For now.

Apple. The latest battle in the patent wars begins Monday, as the smartphone giant heads back to court to take on its biggest rival: Samsung. Both companies are accusing each other of ripping off designs and features of their devices.

BlackBerry. The ailing smartphone maker closed Friday on a nosedive. The declines continue, although well off the 7% shed last week. On the bright side, BlackBerry earned a victory in court over the Typo keyboard case for iPhones. A judge halted sales of the accessory, which looks similar to BlackBerry’s signature smartphone keyboard.
